PYROTECHNIC SIGNAL-TORCH.

QPECIPICATION forming part of Letters Patent No. 329,442, dated November 3, 1885.

Application filed February 19, 1885. Serial No.156,336. (No model.)

. all as will be hereinafter more fully described.

In the accompanying drawings, Figure l is a side view of my improved torch; Fig. 2, a longitudinal central section of the same.

The lettera represents a tube made of sheetzinc, and open on top and bottom. Into the lower end of this tube fits a downwardly-projecting pointed handle, b. This handle is preferably made of wood, and may be either driven into the ground, or it may be grasped by the hand.

dis a drip-cup, which is made of annular form and surrounds the tube a. This cup may be pushed up or down along the tube, and

is held by frictional contact in any position in which it may be placed.

6 is a cap for closing the upper end of tube a. The tube a is filled with an illuminatingcharge. This charge is composed of the following ingredients: three parts of sulphur, one-half part of nitrate of potassium, one part of sulphide of antimony, two parts of realgar, one part zinc filings. A fuse, f, is inserted into the upper end of the charge, as shown. When this chargeis ignited, it will burn down slowly and will consume the zinc tube ain the samedegree as it burns down. In this way the charge will at all times give off its luminosity.

In place of the charge above described, other charges may be substituted; but the charges should always be of such a character that they will consume the tube a in burning down.

I claim as my invenlion 1. The combination of a zinc tube, a, with a charge which consumes the zinc tube in burning down, and with a drip-cup, d, and cap 6, substantially as and for the purpose specified.

2. The combination of zinc tube a with pointed handle I), drip-cup d, and cap 6, and with a charge which consumes the tube in burning down, substantially as specified.

3. The combination of zinc tube a with handle b, drip-cup d, and cap 6, and with a charge composed of sulphur, nitrate of potassium, sulphide ofantimony, realgar, and zinc filings, substantially as specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
